Definitions
- one or two or more of rubbers and elastic bodies such as a thermoplastic elastomer used for an elastic layer (conductive elastic layer) of the conventional charging member can be used.
- the rubbers include: urethane rubbers, silicone rubbers, butadiene rubbers, isoprene rubbers, chloroprene rubbers, styrene-butadiene rubbers, ethylene-propylene rubbers, polynorbornene rubbers, styrene-butadiene-styrene rubbers, acrylonitrile rubbers, epichlorohydrin rubbers and alkyl ether rubbers.
- the MD-1 hardness is preferably not less than 60 degrees and not more than 85 degrees, and particularly more preferably not less than 70 degrees and not more than 80 degrees from the viewpoint of suppressing deformation of the charging member when the charging member is brought into contact with the electrophotographic photosensitive member, which is a charged body.
- the conductive elastic layer preferably has the so-called crown shape, in which the layer thickness in the central portion is larger than the layer thickness in the end portion, in order to uniformly contact the photoreceptor in the transverse direction.
- the hardness of the film can be adjusted by the amount of the compound represented by the formula (19).
- a variety of properties can be given according to the kind of R 72 . Particularly, in the case where R 72 is an alkyl group having 1 to 21 carbon atoms, solubility and applicability are preferably improved. In the case where R 72 is a phenyl group, electrical properties, and particularly volume resistivity is preferably improved.
- a component (A) is a hydrolyzable silane compound represented by the formula (12)
- a component (B) is a hydrolyzable silane compound represented by the formula (19)
- a component (C) is a hydrolyzable titanium compound represented by the formula (13)
- a component (D) is a hydrolyzable tantalum compound represented by the formula (14).
- the amount of water as the component (E) to be added is preferably not less than 0.3 and not more than 6.0 in the molar ratio (E)/ ⁇ (A)+(B) ⁇ .
- the range of not less than 1.2 and not more than 3.0 is more preferable.
- condensation sufficiently progresses, and an unreacted remaining monomer is reduced.
- condensation progresses not too fast, and turbidity and precipitation are suppressed.
- An excessive amount of water as the component (E) increases the compatibility and polarity at the time of mixing with alcohol, and reduces the compatibility with the condensate. As a result, the solution after synthesis is likely to be turbid or precipitated as described above.
- alcohol As the component (F), primary alcohol, secondary alcohol, tertiary alcohol, a mixture of primary alcohol and secondary alcohol, and a mixture of primary alcohol and tertiary alcohol are preferably used. Particularly, ethanol, a mixed solution of methanol and 2-butanol, and a mixed solution of ethanol and 2-butanol are preferable.
